自适应结构综述

开展自适应结构研究的目的是为了衰减与控制大型柔性空间结构的振动,并保持其外形.在这种结构的承力部分集成有作动器、传感器和控制器,可对内部或外部激励自动地作出响应,并进行调整.自适应结构在未来大型空间飞行器中将具有重要的且不可代替的作用,文中对自适应结构的有关技术进行了综合论述,内容包括自适应结构的发展背景、定义与组成、基本概念与理论,以及有关关键技术.

Overview of Adaptive Structures

The technical motivation that stimulated the initial research in adaptive structures was the goals of attenuating and controlling the vibration motion and maintaining the shape of large flexible space structures,which can be adapted through automatical response to internal or external stimulations by direct integration of actuators,sensors and controllers into the load carrying structures.It is expected that adaptive structures will play an important and irreplaceable role in meeting the performance requirements of future large spacecrafts. An overview of the technology related to adaptive structures is presented in this paper. Included are the development background, definition and constitution, basic concept and theory, as well as critical technologies of adaptive structures.
